3 Claims.

This invention is a hanger for supporting and disposing marine cables, pipes, conductors and the like in ships, buildings, and other places, and it is an improvement over the hanger disclosed in the joint application of the applicants and Charles A. Slater, Ser. No. 554,916, .filed Sept. 20, 1944, for Hanger.

The general object of the invention is to provide a more simple and improved hanger of the character stated, which may be more readily, conveniently and satisfactorily assembled for supporting and disposing Cables, pipes, conductors or the like, of the same or of different diameters, in suitable arrangement in ships, buildings and Other objects and advantages will appear hereinafter as this specification progresses.

The invention is illustrated in the annexed drawing which forms a part of this specification and in which:

Fig; 1 is a side elevation of our invention shown partly broken away and in section, and showing several cables clamped thereon.

Fig. 2 is a .plan view of our invention as shown in Fig. 1.

Fig. 3 is a bottom plan view of our invention as shown in Figs. 1 and 2.

Fig. 4 is a transverse Vertical section of our invention takenon line 4-4 of Fig. 1.

Fig. 5 is a perspective of the clamp strap of one of the clamps.

Fig. 6 is a perspective of the bridge bar of one of the clamps for bridging the slot in the hanger bar and to be engaged by the clamp screw.

Fig. 7 is a perspective of the connecting pressure bar for connecting the ends of the clamp strap of one of the clamps, and through which the clamp screws are threaded for engaging the bridge bar of the clamp for applying pressure to the clamp to clamp a cable pipe or the like on the hanger bar.

Fig. 8 is a view like Fig. 4 of a modification of our invention.

Referring more particularly to the drawing in which the same parts are designated by the same reference numerals in all of the figures, our invention includes generally a hanger bar I and a plurality of clamps 2 for clamping Cables, pipes, conductors and the like 3 on said hanger bar.

The hanger bar I is preferably of channel form comprising a base wall 4, and side fianges 5 depending from the side edges of said base wall, and said hanger bar is bent upwardly near its ends into securing members 6, in the base wall 4 of which are provided bolt openings 1 to receive bolts 8 for detachably securing said securing members 6 to suitable supports 9, respectively. The base wall 4 of the hanger bar I is provided with an Velongatedrslot I0, extending longitudinally of said bar substantially the length thereof between the end securing members B for the purpose hereinafter described.

Each of the clamps 2 comprises a V-shaped clamp strap II, a pressure bar I2, one or more bridge bars I3 and one or more clamp screws I4 according to the size of the clamp and length of the pressure bar IZ. The clamp strap II is provided with rectangular openings I5 in the ends thereof, respectively, to receive the respective ends of the pressure bar IZ.

The ends of the pressure bar I 2 are bent at right angles in the form of end flanges IB, and

said bar ends are extended through the openings p I5, respectively, in the ends of the clamp strap II,V with said bar ends resting on the lower edges of said openings, respectively, and said end fianges I6 engaging the outer side of said clamp strap below said lower Vedgesof said openin'gs I5, respectively, for holding the clamp strap II around a cable, pipe, conductor, or the like 3, as shown in Fig. 1 of the drawing. The pressure bar I2 is provided with one or two threaded openings I'I, to receive one or two of the clamp screws I4, which are threaded upwardly through said openings.

Each bridge bar I3 is offset upwardly as at I8, between its ends for a portion of its length slightly less than the width of the slot IIJ in the base wall 4 of the hanger bar I, so that said offset portion will fit within said slot between the side edges th'ereof, with said bridge bar extending across said slot and its end portions I9, beyond said offset portion engaging the under side 'of said base wall 4 at opposite sides, respectively, of said slot IO, as shown in Fig. 4 of the drawing. The offset portion of the bridge bar I3 is provided intermediate at its ends with an opening 20 in which the end of one of the screws I4, threaded through an opening I1 in the pressure bar I2 is turnably riveted as at 2|. One or two of the bridge bars I3 'are used in each clamp 2 according to the size of the clamp and the length of the clamp pressure bar I 2.

The operation of our invention is as follows:

Cables 3, for example, disposed in any suitable arrangement, are extended across and over the hanger bar I and rest upon the upper side of the base wall 4 of said hanger bar, and said cable pipes, conductors or the like are clamped on said hanger bar by the clamps 2, respectively. The

straps 1 1 of the clamps 2, respectiveiy, are slipped over said cables, respectively, and the ends of said straps extended downwardly through the slot 111 in the hanger bar 1. The ends of a pressure bar 12 are extended through the openings 15, respectively, in the ends of the strap 11 of each of said clamps 2, and the end fianges 16 of the pressure bar 12 are slipped over the outer sides of said strap ends, respectively, until the ends of the pressure barengage the lower edges of said Strap openings 15, respectively, while the bridge bar or bars 13, which are turnably riveted on the upper end of the screw or screws 14 in said pressure bar 12, are placed with their oset portion 18 within the slot 19 of the base wall 4 of the hanger bar 1 and with the end portions 19 of the bridgebar or bars 13 against the under side of said base wall at the sides, respectively, of said slot. V The clamp screw or screws 14 of each clamp 2 are then turned so as to draw the pressure bar 12 downwardly, and force the bridge or bridges 13, which are turnably riveted on the ends of said screws, upwardly, Whereupon the pressure bar 12, with its ends engaging the lower edges of the openings 15, re-

spectively, in the ends of the strap 1 of the clamp, M

draws said strap downwardly against the cable 3 over which said strap extends and said strap draws said cable against the base wall 4 of the hanger bar 2, while said screw or screws 14 force said bridge or bridges 13 upwardly until the end portions 19 of said bridge or bridges 13, engage the under side of the base wall 4 of the hanger bar 1 at opposite sides of the slot 111, in said base Wall, and the offset portion or portions 18 of said bridge or bridges are projected into said slot, thus firmly clamping the cables 3 firmly upon the hanger bar 1.

In the modification of our invention shown in Fig. 8 there is no bridge bar V13, but an outwardly bowed bridge bar 25 of spring steel is placed across the lower side of the hanger bar 1 with its ends resting against the lower or outer edges of the said flanges 15 of said hanger bar, which bridge bar 25 is provided with an unthreaded opening 26 intermediate its ends, through which opening the screw 14 is loosely extended With the head of said screw engaging the outer convex side of said bridge bar, and with said screw engaging the threaded opening 11 in the pressure bar 12, for drawing down said pressure bar and the clamp strap 11, for clamping a cabie 3 on the hanger bar 1. The bridg bar 25 is formed at its ends with upturned fiang s 21 for engaging the outer sides of the fianges 5, `respectively, of the hanger bar 1 for preventing Vdisplacement of said bridge bar with relation to said flanges 5 of the hanger bar 1.

' We claim:

1. A hanger as disclosed including a hanger bar provided With a slot therein extending longitudinally thereof, over which hanger bar may be transverseiy extended cables, and clamps for clamping said cables on said hanger bar, each of said clamps comprising a V-shaped strap provided with openings in its ends, respectively, which V-shaped Strap is placed over a cable with its ends extended downwardly through said slot in` said hanger bar, a pressure bar With its ends extended through said openings, respectively in Said strap, a clamp screw threaded through said pressure bar7 and a bridge bar placed against the' under side of said hanger bar across said slot in said bar, which bridge bar is engaged by said screw for enabling said screw, through said pressure plate and said clamp strap, to clamp said Cable on said hanger bar.

, 2. A hanger as claimed in claim 1 in which the end of the clamp screw is turnably riveted in the bridge bar.

3. A hanger as claimedin claim 1 in which a portion of the bridge bar is offset .to be projected into the slot in the hanger bar, when the bridge beyond said offset is forced against the under side of the hanger bar by the clamp screw, and the end of the clamp screw is turnably riveted in the bridge bar.
